但造雪机有一个无法突破的物理限制：它需要足够低的气温才能工作。传统造雪机依赖湿球温度（指对一定容积的空气进行加湿，达到饱和状态时所达到的温度）通常需要在零摄氏度以下运转。高温造雪机虽然可以在零摄氏度以上运行，但成本更高，效率也会随气温上升而急速下滑。
State functions are a compelling feature that allow data to be incrementally summarized for later queries using Aggregate functions. However, materialized views that compute many state functions — especially quantile states — can be CPU intensive and lead to slow inserts. Be deliberate about which aggregations you precompute and ensure the query-time savings justify the insert-time cost.
